TILE STOVE.

Application tiled November 18, 1891 Serial No. 411,968. (No model.) Patented in Austria-Hungary October 8, 1889, No. 16,316 and No. 44,852; in Germany January 24,1890, No. 50,514; in Norway March 12, 1890, No. 1,558; in Denmark March 15, 1890, No. 642,' in Sweden October 23, 1890, No. 2,622, and in Switzerland September '7, 1891, No. 1,387.

To @ZZ whom it may concern:

Be it known that I, REINHOLD MEYER, a subject of the King of Bavaria, residing at Wildburgstetten, Bavaria, Germany, haveinvented certain new and useful Improvements in Tile Stoves, (which have been patented in Austria- Hungary, No. 16,316 and No. 44,852, dated October 8, 1889; in Sweden, No. 2,622, dated October 23, 1890; in Germany, No. 50,514, dated January 24, 1890; in Norway, No. 1,558, dated March 12, 1890; in Switzerland, No. 1,387, dated September 7, 1891, and in Denmark, No. 642, dated March 15, 1890,) of which the following is a specification.

It is a well-known fact that the tiles of the form at present employed become coated with soot very rapidly and that their recesses are not easily accessible, and the process of cleaning them is hence attended with difficulty. On the narrow sides of the stoves, where the so-called sight-openings are located, there is no possibility whatever of cleaning. Inasmuch as the soot materially impairs the conduction of the heat, it follows that the tiles or lire-brick are heated with difficulty and that their heating effect is not in a proper relation to the amountof fuel consumed. These defects are radically removed in the improved stove-tiles hereinafter described.

In the drawings, Figure 1 represents a stovetile in cross-section; Fig. 2, a vertical section showing one ue; Fig. 3, a plan view of one layer of tiles with a flue-plate, and Fig. 4 a vertical section of a tile oven provided with the improved double-walled tile.

An additional plate a is laid upon the lateral anges of the tile, thus closing the same whereby the access of soot and ashes to the interior of the tile is prevented. This plate, being of equal thickness throughout, may be made very thin without incurring the danger of cracking. It is not necessary, moreover, to glaze the same, and it hence remains porous. These properties both combine to induce a rapid and effective transmission of heat, such as cannot possibly be attained by the usgalm stove-tiles, for the latter must be madivery thick on account of the designs, whqse contours are often of great depth, and

their only heat-transmitting surface is, furthermore, coated with a layer of glazing, closing its pores.

To assemble the tiles to form a stove, the same may be constructed as follows: The innproved tiles are provided at their tops and bottoms with a deep recess or rabbet having a rib b and athroat c, the latter having openings d drilled or cut into them. These openings permit the expansion of the air in the interior of the tile and the circulation of the same. These rabbets afford a joint for the attachment or putting in place the hollow plates e. These hollow plates take the place of the flues formed of single massive plates and may also be substituted for the customary so-called sight-openings, (usually made of sheet iron,) as indicated, e. g., in the vertical section of the stove. The hollow plates e are provided with openings at their front or rear ends, andin the corner-pieces these openings are provided in the sides. These openings serve to admit the hot air issuing from the tile and to convey it in the desired direction. These plates e are, moreover, provided with two enlargements or ribs f g, Fig. 2, at the points where they are supported by the tiles, the first to prevent the warping of the stove as it expands when the fire is started, the second to provide a small clearing or free space, which facilitates the unimpeded influx of the heat, Fig. 1. For this purpose the outer enlargement is provided with anyT desired recesses or indentations, as at h. These hollow plates have the advantage, in addition to that already referred to, of absorbing the heat developed in the interior of the stove, and which with the dues now in use escapes through the chimney unutilized, and conveying the same outwardly. They thus increase in a considerable degree the heatingsurface, and hence also the heating effect of the stove, because the upwardly-flowing heated gases impinge particularly against these hollow plates with increased force. At the points where the smoke and product-s of combustion are to pass from one layer of tiles to the next above the plate is provided with suitable recesses or mortises. Wherea Iiue is omitted, a piece or strip similar in shape to the ends of the iiues is inserted into the gap formed by the mortises or rabbets on the tiles (see strip B Fig. 2) to prevent the admission of smoke and to obviate any interference with the circulation of the air to the connecting-plate next above.

It is obvious from the above that a stove constructed of the so-described tiles or flues 1o and which presents flat surfaces at all points in its interior may be cleaned very easily and thoroughly and that the utilization ofV heat therein is the highest conceivable.

The inner plates a of the tiles, as well as the hollow plates e, are preferably made of fireproof material for the purpose of durability. No change occurs in the building of the Stover nor is any necessary in putting the flues in place. The tiles are beveled, as will appear from the above, for the purpose `of making the necessary joints with clay.

The necessary moldings are formed similarly to the tiles. These moldings might, e. g., be formed integral with the iiues, and the fines may be so constructed that their or namental front edges may serve as an intermediate molding.

The tilesfor the lowerrnost part of the stove are provided with slots or openings on their heated air rising through the interiors of the tiles and passing oif at the top by the colder air on the iloor, whereby a circulation and a uniform temperature of the. entire body of air in the space to be heated is obtained.

What I claim, and desire to secure by Letters Patent, is

' 1. Atile stove constructed of superimposed layers of hollow intercommunicating tiles to form the outer walls, in combination with hol- 4o low flue-plates, as e, communicating with the hollow tiles at their points of connection, substantially as set forth.

2. In a tile-stove, the combination of superimposed layers of hollow tiles provided with 45 rabbets, as a, ribs, as b, and throats, as c, with bellow Hue-plates, as e, arranged between the hollow tiles, and strips, as B, arranged between the said hollow tiles at the points where no flue-plates are arranged, the line-plates `5o being provided with mortises and the hollow tiles with openings at their tops and bottoms to permit the circulation of air, as described.

In testimony that I claim the foregoing as my invention I have signed my name in pres- 55 ence of two subscribing witnesses.

REINHOLD MEYER.
